REET Level 2 study notes
Statistics and Data Handling
Statistics and Data Handling for REET Level 2 means collecting, organising, representing and interpreting small class-level data. The RBSE syllabus names collection and classification of data, frequency distribution table, tally marks, bar graph, histogram, circular graph and graph types. A teacher must help Class 6-8 learners distinguish raw data from organised information, bar graph from histogram, and mean from median and mode.
Key points
- RBSE Level 2 explicitly names data collection, classification, frequency tables, tally marks, bar graphs, histograms and circular graphs.
- Data handling follows four verbs: collect, organise, represent and interpret.
- Mean, median and mode answer different questions: fair share, middle value and most common value.
- Bar graphs suit separate categories; histograms suit grouped continuous intervals.
- Circular graphs show parts of one whole and need complete category coverage.
- Tally marks and frequency tables bridge raw observations and graphs.
- Named-child classroom tasks reveal scale-reading, interval-making and overclaiming errors.
- A conclusion must match the data source, sample size and question asked.
